i have published the work-in-progress state of my unicode renderer in pure lua. the README also contains some examples and explanations on how you can cut texture size in minetest by a lot by sidestepping the whole optipng thing. this is probably interesting to engine developers, i believe this is the first easily-accessible code that even a super-lazy dev could use for texture encoding benchmarks in terms of encoding time and |
| 13:27 |

payload. https://git.minetest.land/erlehmann/tga_unicode_renderer |
| 13:28 |
erle |
and yes, i was surprised by the results myself, especially for the checkerboard pattern thing |
| 13:32 |
erle |
since my goal is to have unicode on signs i would appreciate it if anyone on the input side of things could look at this example rendering and tell me if there exist characters that can not be input |

if you see any engine issues regarding my goal of fully backwards-compatible unicode on signs, please tell. as far as i can tell, my envisioned solution will work at least as far back as minetest 5.3 and require no new engine features (see readme for details). |
| 13:37 |
erle |
in particular, i would like to know if there are issues having big textures |
| 13:38 |
erle |
or if there is anything i should do to not fill the clients memory with garbage |
| 13:39 |
erle |
(the garbage issue is one of several reasons why xmaps does not have live-updating maps, i fear the client caching a texture for each change in the map) |
| 13:43 |
erle |
by the way, if anyone feels like fixing minetest.encode_png() to be able to compete with tga_encoder() in terms of features, feel free – but know that this is most likely a waste of your time, as the space-time tradeoff will *never* be in your favor for optimized PNG files (assuming no player wants to wait 20 seconds for their super-optimized sign texture to appear). |
| 13:46 |
erle |
oh yeah, i already wrote it in #minetest – but you can probably reduce the transfer size of almost all textures by about 30% or so if you support .tga.z as a format (with fallback to sending .tga to older clients). this is probably by far the easiest thing you can do in terms of slashing teture filesize. |

btw, the shibboleths for not having understood the technical details are a) disputing the benchmarks without running them yourself b) proposing to compress all TGA files automatically (there is a simple reason why this does not work and it is so obvious i have not written it down, the random noise thing is a red herring) |
| 13:52 |
erle |
by which i mean, i'd appreciate input from people knowledgeful in the problem space |
| 13:52 |
erle |
thank you for coming to my ted talk :) |

<grorp> Merging #13768 in 15 min |

grorp why did you keep the function name the same when you radically changed the signature? |
| 19:44 |
MTDiscord |
<grorp> If you mean the one of buttonbar_create, it's an internal function so why would renaming it be necessary? |

| 20:57 |

grorp if it is an internal function and you fix all callsites, i understand completely |
| 20:58 |
erle |
grorp i am so disappointed, i thought maybe this was a new coordinate exploit |

> Modify a client to log the addition of ParticleSpawners |
| 20:59 |
erle |
grorp did you use coras cheatclient for that or what? |
| 21:01 |
MTDiscord |
<grorp> No, I didn't. Did they write one? I only know the one written by Fleckenstein. |
| 21:02 |
erle |
grorp it is called waspsaliva and last time i used it we also used it to detect particle exploits |
| 21:02 |
erle |
i think it is a fork of lizzys dragonfire? |
| 21:02 |
erle |
not sure |
| 21:03 |
erle |
https://repo.or.cz/waspsaliva.git this seems a bit old, but look at it |
| 21:03 |
erle |
a bunch of these APIs can help a lot with debugging |
| 21:05 |
erle |
grorp cora pointed me to https://github.com/dragonfireclient/dragonfireclient so ig she contributes to upstream dragonfire now |
| 21:09 |
MTDiscord |
<grorp> Both PRs merged now. |
